A system goes from A and B via two processes. I and II as shown in figure. If `DeltaU_1 and DeltaU_2` are the changes in internal energies in the processes I and II respectively, then

A

`DeltaU_(1) = DeltaU_(2)`

B

relation between `DeltaU_(1)` and `DeltaU_(2)` cannot be determined

C

`DeltaU_(2) gt DeltaU_(1)`

D

`DeltaU_(2) lt DeltaU_(1)`

Text Solution

Verified by Experts

The correct Answer is:
A
The change in internal energy does not depend upon path allowed by the process. It only depends on initial and final states.
Hence, `DeltaU_(1) = DeltaU_(2)`
